Abstract
The factors which influence the voice quality in multi-media conference on IP network, such as delay and the accumulation of delay is analyzed. A scheme which adopts mixing buffer and method of uniform mixing period to increase the quality of mixed speech is proposed. The prototype of multi-media conference system which using this scheme proves that the quality issue of speech mixing can be solved well, and the speech quality is good in the local area network.
